Hield aviation
I have been hiring R22's from Bob for a while. If your wanting instruction peter Bolton is pretty good. I have allways found them a friendly bunch.
Maintance is pretty good and helicopters are allways clean and luck well maintained.
They don't allways have R22's available though - I use Sandtoft helicopters as well. these are a good friendly bunch. I prefer the annual check with geoff Day based at Sandtoft.
I can recommend Hields and Sherburn, just don't get involved in the petty politics. Sherburn have been very unlucky with the comittee for the last few years.
